Patents by Inventor Robert X. Monchamp

Robert X. Monchamp has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method of starting spark-ignition direct injection (SIDI) engines
    Patent number: 9234475
    Abstract: A cold start control module for a direct injection engine includes a fuel flow determination module and a cylinder activation/deactivation module. The fuel flow determination module determines a requested fuel flow. The cylinder activation/deactivation module deactivates at least one of cylinders when the requested fuel flow exceeds a maximum fuel flow of the fuel pump during cold start.
    Type: Grant
    Filed: December 16, 2008
    Date of Patent: January 12, 2016
    Assignee: GM Global Technology Operations LLC
    Inventors: Jesse M. Gwidt, Michael N. Kotsonas, Robert X. Monchamp, Karen Margaret-Bell Gwidt
  • Model-based fuel control for engine start and crank-to-run transition
    Patent number: 7793641
    Abstract: A fuel control system for regulating fuel to cylinders of an internal combustion engine during an engine start and crank-to-run transition includes a first module that determines a plurality of step-ahead cylinder air masses (GPOs) for a cylinder based on a plurality of GPO prediction models. A second module regulates fueling to a cylinder of the engine based on the plurality of step-ahead GPOs until a combustion event of the cylinder.

  • Utilized function for fuel dynamics during engine start and crank-to-run transition
    Patent number: 7647162
    Abstract: A fuel control system for an internal combustion engine includes a first module that determines a corrected injected fuel mass based on an engine temperature and a measured burned fuel mass and a second module that determines a raw injected fuel mass based on the corrected injected fuel mass and the engine temperature. A third module regulates fueling to a cylinder of the engine based on the raw injected fuel mass.
